THE PRESENCE OF A GREEN SLIME OR THE GROWTH OF ALGEA. Onother view: If talking about liquid broth medium in laboratory then it can be estimated by the increase in turbidity which is caused by increase in number of microbial cell and we can observe it by spectroscopy.

What is basal medium?
A basal medium is a growth medium which incorporates a genetic material such as yeast extract of unknown precise composition.
Which environment has the most total bacteria either petri dish or liquid agar?
Actually the liquid agar medium is used in the petridishes to grow the colonies of bacteria. The nutritional environment available to the bacteria results in to faster growth of their colonies and also they can be used for the experiments more rapidly
What is bacterial suspension?
Refers to the bacteria suspended on the petri dish or growth medium.
How does a smear preparation of cells from a liquid medium differ from preparation of cells from a solid medium?
In liquid medium one starts by placing one or two loopfuls of the liquid medium directly on the slide. From solid media such as nutrient agar. One starts by placing one or two loopfuls of water on the slide and then using an inoculation loop to disperse the organisms in the water. Bacteria growing on solkid media tend to cling to each other and mus be dispensed suficiently by dilutiion in water.
The tryptophan operon is a repressible operon that is?
Turned off whenever tryptophan is added to the growth medium
What is growth of plants in liquid medium called?
hydroponics
What is growth of crop plants in a liquid medium called?
hydroponic
What is agar medium?
It is a medium that support the growth of cells or microorganisms. It is usually a liquid or a gel and there are different agar mediums for different types of cells.
What is the difference between liquid and solid medium?
In wave motion, the media are said to be liquid and solid according to the states of media themselves, that is, if a medium is in solid state then the medium is said to be solid medium and if the medium is in liquid state, then the medium is said to be liquid medium.
Why there is more bacteria growth in liquid vs solid medium?
it is more on liquid because moist attracts more microorganisms than on dry surfaces it is more on liquid because moist attracts more microorganisms than on dry surfaces
What are advantages of a solid?
The culture on solid media (agar) surface aids microbiologist in identifying microorganism because individual species often from colonies of characteristic size and appearance. When mixed population has been plated properly, it sometimes is possible to identify the desired colony based on its overall appearance and use it to obtain a pure culture. Whereas in liquid broth we get mixed culture and can not identify the seprate colony of any microbial species in that mixed culture.
What are the formats of Keratinocyte Growth Medium?
• Basal Medium - contains no growth factors cytokines, or supplements• Supplement Kit - growth factors, cytokines, and supplements• Medium Kit - basal medium and Supplement Kit packaged together
When a substance is added to solid medium which inhibits growth of unwanted bacteria but permits the growth of wanted bacteria the medium is known as?
selective medium
Signs that your growth spurt will occur soon?
Age and time are some of the signs that growth will sprout soon.
What is HS medium?
High Salt Medium Used as a medium for algal growth environment
What is colloidal emulsion?
An emulsion has liquid particles dispersed in a liquid medium An emulsion is a type of colloidal solution consisting of liquid(dispersed phase) mixed in another liquid(dispersing medium), so the mixture is an emulsion.A gel is a colloid of liquid(dispersed medium) mixed with solids.(eg-butter)
What does a culture medium provide to a living thing?
Culture media in microbiology is a media where microorganisms like bacteria from a sample is grown into colony for the identification of particular organism.eg-simple media like blood agar,choclate agar
